  1. Federated Searching Do Undergraduates Prefer it andDoes it Add Value? C. Jeffrey Belliston http://webpub.byu.net/jlh39/ula/2007/ Jared L. Howland Brigham Young University 2007 Utah Library Association Annual Conference May 18, 2007

  2. Poll:Federated Searching Experience • Considering implementing • Actively planning for implementation • Implementing or pilot project • Fully implemented – less than happy with • Fully implemented – happy with C. Jeffrey Belliston http://webpub.byu.net/jlh39/ula/2007/ Jared L. Howland Brigham Young University 2007 Utah Library Association Annual Conference May 18, 2007

  3. Study Background 1 • Consortium of Church Libraries and Archives (CCLA) • Five academic and several special libraries • All academic institutions interested • Competition with Google • Desire to promote scholarly subscription resources in an effective way • Expose less-used content to greater use C. Jeffrey Belliston http://webpub.byu.net/jlh39/ula/2007/ Jared L. Howland Brigham Young University 2007 Utah Library Association Annual Conference May 18, 2007

  4. Study Background 2 • Before implementation • Demos from leading vendors for CCLA libraries • Discussion and input from library staffs • “Let technology mature” • “Opt for leading edge not bleeding edge” • CCLA Directors decided to license • Initial 3 year agreement (expires 2007) • Actual implementation left under local control C. Jeffrey Belliston http://webpub.byu.net/jlh39/ula/2007/ Jared L. Howland Brigham Young University 2007 Utah Library Association Annual Conference May 18, 2007

  5. Study Background 3 • Impetus for study came from impending renewal • Is federated searching doing what we hoped it would? • Four questions • Does federated searching save time? • Does federated search satisfy students' information needs? • Do students prefer federated search to the alternative of searching databases individually? • Does federated searching yield quality results? C. Jeffrey Belliston http://webpub.byu.net/jlh39/ula/2007/ Jared L. Howland Brigham Young University 2007 Utah Library Association Annual Conference May 18, 2007

  6. Study Methodology – Preparation 1 • Hoped to do at all four institutions • Received IRB approval at all four • Dropped LDS Business College due to poor response • E-mailed potential undergraduate participants • Decided upon hypothetical research questions (both biology) • With faculty and librarian help, created subjective grading rubric C. Jeffrey Belliston http://webpub.byu.net/jlh39/ula/2007/ Jared L. Howland Brigham Young University 2007 Utah Library Association Annual Conference May 18, 2007

  7. Study Methodology – Preparation 2 • With vendor help, designed implementation-neutral web interface • Did not want study interface to look like any of the institutional interfaces • Wrote and tested instructions for data collection • Printed instructions and questionnaires • Scheduled rooms and respondent appointments • Suggested 30-60 minutes as typical timeframe • Provided, on our end, a minimum of two hours to complete C.
